A guy's hair should be masculine - men should look like real men," says stylist Mr Tyler Johnston, the man responsible for Mr David Beckham's manly mane, and who kindly executed all the cuts we show you here. "There's a certain old school, barbering technique that has come back to the way men wear their hair and whether that's thanks to Mad Men, or the resurgence in rock'n'roll, it's something I'm particularly fond of. These cuts, photographed on six men for different professions, illustrate a modern approach to such classics." Some are simple and nostalgic; others demand a certain degree of chutzpah. But you're soon going to see a lot more of these popping up on a head near you.
